Question

It takes light to roughly `3.0 times 10^9` seconds to travel one meter. How do you write this time in standard form?

Answer 1

`3.0xx10^-9 = 0.000,000,003` seconds

Explanation:

I am presuming that you meant `3.0xx10^-9` seconds, as the speed of light is very fast so it should take a very short time to travel one meter rather than a very long time.
If you are really interested, `3.0xx10^9` seconds = `3,000,000,000` seconds.
